The present invention relates, to dental "tools and more particularly to torceps which embody novel features of construction,

whereby they canbe used to, the best possi ble advantage for the extraction, of teeth. It hasbeen found that there are "certain V of .thejteeth. which require a rotary moveamong the objects of the presentinvent-ion 5 are to provide forceps havlng handleswhich are specially constructedto facilitate the 013-. x tammg of: a grip'which will be: advantageo'us cially where, this rotary motion is desired;

. Further objects of the invention are to provide dental forceps whicharesimple' and inexpensive in construction, which canbe I 'anc'ed tool. r

For afulljunderstanding ofthe invention f reference is to be had to the following de 7 scription and accompanying drawings, in

.Wl1i I Eigure 1,is a side elevation, of a pairof dental forceps'which are'constructed in accordance with the invention.

1 Figure12is a slmllarview showing a slight modlfication, and

enlarged transverse sectional view taken on the line 3 3 of Fig- .ur sl-m Figure 8- duced scale showing thetmanner of using the forceps for extracting teeth.

Corresponding and like parts are referred I to in the following descrlption and indi- L "cated on all of the views of the ,drawingsby;

like reference characters. j

. Referring to Figure 1 of the :dra wingathe jnumerals l andQdesignate a pair of handles nd thereof in a laterally. extending hand hold 5,- Which iscurved and shaped to fitfthe;v

r looseningand removingteeth, espel a diagrammaticviewon a'reof a pistol. The handle 2 has a substantially i spaced and parallel relationto the handle-l,

and terminates in a laterally extending tin ger piece 6 which has the same general direction as the handheld 2 but is spaced there from.

,The'finger piece 6 may have oneor more finger receiving notches or depres'sions'Y, depending upon the number "of-fingers which are intendedto be used-tor engaging thefinger piece. As shown on Figure 1, the

finger piece 6 has two of the notches 7 and a a portion of thehandle 5jwhich extends beyond, the finger piece isjprovided upon the inner side thereofwith a notch 8;

The handle 1 'COI1Stltllt6S what may be termed a'master handle, and-the force applied for'loosening. and extracting the tooth 'is applied to this handle, the otherv handle 1 having. merely a suflicient amount of force applied thereto to. maintain the proper grip upon the tooth. Inusing the tool the hand- 'hold 5 is received within the palm of the hand and'grippedin much the same manner as the handle of apistol. The forefinger extends around the hand-hold along the handle 1, being received within a" seatior depression 9 in the lower side thereof. In a similar manner the thumb of the hand er;- tends around the handheld. on' the opposite side thereofandalong the handle 2 being received Within a. depression 10. formedGin the top of; the handle. The depressions 9 and 10 are shown q uite clearly by Figure 3, and the handles 1 and 2 are symmetrically shaped, having corresponding depressions 9 and 10 on oppositesides thereof so that they canbe used interchangeably with either the right hand orthe left hand. The respective a:

handles are thus engaged by the thumb and the handles bythe thumb and. forefinger for moving the handles apart to open the ,javv's.

* piece 6 and pullthe finger piece towardthe hand-hold with a suflicient force to cause the jaws 4 to grip the tooth to be extracted. The, curvature of the handles facilitates the use ofthe 1:001. On Figure 4 the forceps are shown in the position assumed when will be observed that the curvature of the handles provides a clearance space for the nose and features. a similar manner One or more of the fingersengage the fin er pulling one of the front lower teeth, and it forefinger, so that pressure can be applied to,
